Mario ordered a pizza for dinner. When it arrived, Mario quickly ate

Question

of the pizza. While Mario was getting napkins, his pet poodle ate
of the pizza.
about what percent of the pizza is left

Answer 1

Let's say the pizza was divided into 100 equal parts.

Mario ate 1/3 of the pizza, which is (1/3)*100 = 33.33% of the pizza.

After Mario's poodle ate some, let's say there were x parts of the pizza left.
The poodle ate 1/5 of x parts, which is (1/5)*x = (x/5) parts of the pizza.

So, the remaining percentage of the pizza is (100 - 33.33 - (x/5))%

We cannot determine the exact percentage without knowing the value of x, the remaining parts after the poodle ate some of the pizza.
